After looking at some posts i see there is people that have huge boost peaks, is this normal.

Wouldnt a more progressive curve be better for acceleration and limiting wheelspin, yes it wont be as entertaining but wheelspin doesnt win races.

Looking at my old graph i was peaking 16.4 and falling to 16.1.

Wouldnt this be better than a 4 - 6 psi peak coming onto boost.
